FEX Extruder Gearboxes – Single-Screw Extruders
Custom-made Extruder Gearboxes
The flat extruder gearbox of the FEX Series has been specially developed for the extrusion process in the plastics industry and for recycling plants with a view to the axial loads that occur. The gearbox – available in Z or U shape – is characterized by its high power density and compact design.
The sizes range from a centre distance of 125 to 630 mm and have been dimensioned based on the respective screw diameters. The torques of these models lie in a range of up to 200,000 Nm with freely selectable gear ratios.
